SPECIFICATION formingpartof .Letters Patent No. 233,255, dated October 12. 1880.

Application filed July 3, 1880. (No model.)

To all whom it may concern:

Be it known that LwlLLlAMKlMBLE, of Goatesville, in thecounty of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Fastenings for Carriage-Curtains; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and t0 the letters and figures of reference marked thereon.

This invention has relation to fastenings for carriage-curtains; and it consists in the improved features of .construction and combination hereinafter fully described, and particularly pointed out in the claim.

Figure 1 of the drawings represents a side View of the eyelet or locking-plate and the fastening-stud. Fig. 2 is a detail view of the crown-piece of the locking-plate. Fig. 3 is a detail view of the interior annular perforate piece of the locking-plate. Fig. 4 is a detail view of the locking slide or latch and its operatingspring. Fig. 5 is a side view of the rear face of the locking-plate; and Fig. 6 is a vertical transverse sectional view of the locking-plate applied to the carriage-curtain and in place upon the fastening-stud.

In the carriage-curtain fastenings heretofore employed a leather patch fastened in a slit made in the curtain was perforated and slipped over the ordinary fastening-stud, and was objectionable in this, that when the leather was new it was quite stiff, and considerable difficulty was experienced in placing it upon the stud. Besides, after it had been in use some time it became worn, and the perforation enlarged to that extent that it would not retain its place upon the stud, and therefore became practically useless and required to be replaced by a new one of similar structure and like defects. By my improvement these defects are obviated, and a more durable and efficient fastening is obtained.

In carrying out my invention I employ an annular crown-piece, A, having a depending annular flange, B, provided with a rectangular notch, O, and long prongs or teeth D and short prongs E. This crown-piece is also perforated or provided with a circular aperture,

G, at its center. A second annular piece of metal, I, slightly greater in diameter than the crown-piece A, is provided with apertures J, near its periphery, through which apertures the prongs or teeth D and E are to pass when the two pieces are put together. This metal piece I has a central opening, K, corresponding in size with the opening Gin the metal crown-piece A, and has studs L L struck up from the body of the piece I, one at each side of the opening K, as shown in full lines in Fig. 3, and in dotted lines in Fig. 1. A latching-slide, M, struck up from sheet metal, has an opening, M, corresponding in size with the openings G and K near its middle, is bifurcated at one end at O to receive a spiral or other spring, 1?, and provided at the other with a reduced neck and finger-piece, Q. The latching-slide M is placed between the crownpiece A and the metal piece I, the neck Q resting inthe notch C. One end of the spring P bears against the inside of the flange B, and the other end against the end of the bifurcation 0, to press the shoulders R of the slide against the flange B, and hold the stud in a normal position, which causes it to partly close the aperture formed by the registered openings G K, as shown in Figs. 1 and 6. The studs L L form guides for the latching-slide M. The short studs or prongs E, after havin g been passed through their appropriate apertures J, are bent up against the under face of the metal piece I, to hold the plates A and I together. The curtain is then punched and slit to .register with the openings G and K and the holes J, through which the long prongs D have been passed, and the said prongs are passed through said slits. An annular plate, S, of a diameter slightly smaller than the piece I, perforated at T to register with the openings G and K, is then placed against the rear face of the curtain, and the prongs D bent up against it to hold it in place. The foregoing parts comprise the locking-plate.

A studded or headed nail, U, having its head beveled at V, is provided with a notch, W, in one side of its face, and the under side of this notch, or the side farthest from the head of the stud, is beveled at X, as shown in Fig. 6. The bevels on the fastening-stud facilitate the entrance of the stud to the eye of the locking-plate. To unfasten the lockingplate it is only necessary to press upon the latching-slide M and cause its opening to registerwith the openings in the plates A, I, and S.

I am aware that a metal cap having a bifurcated gravitating slide for embracing the neck of a headed nail has been used heretofore, as shown in Patent No. 125,502 of April 9, 1872; but in that case the slide needs to be locked by hand, and as there is no spring to retain it in place it is liable to be switched or jarred from its place. Besides, the cap therein shown is of a different and more costly construction than mine, and is not made claim to herein.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

of two witnesses.
